Safeguarding Your Mobile Banking App: 4 Essential Elements to Ensure Its Security

Introduction

Mobile banking applications have gained significant popularity, providing customers convenient access to banking services anywhere, anytime. Gartner predicts a compound annual growth rate of 29.97% for BaaS engagement among banks and nonbanks up to 2030. Despite the convenience these apps offer, security concerns have resulted in breaches of banks and consumer accounts worldwide, highlighting the need for greater attention to their security. As mobile banking continues to grow, banks must prioritize mobile banking application testing to ensure their customers' information security. Only by enlisting the expertise of mobile security specialists can banks fully mitigate the risks and provide their customers with the seamless, secure banking experience they deserve.

How SREs Mitigate Vulnerabilities in Mobile Banking Apps

As mobile banking apps become more sophisticated, APIs are crucial in enabling seamless and secure user experiences. APIs power essential functionalities, from backend data transactions to real-time updates, creating a dynamic yet complex ecosystem. However, this reliance on APIs introduces potential vulnerabilities, including the emergence of unmanaged APIs, known as shadow APIs, and challenges related to backend security, data integrity, and compliance.

Risks Associated with APIs in Mobile Banking Apps

APIs, while integral, present various security and operational challenges if not properly managed:

• Data Exposure: Inadequately secured APIs can allow unauthorized access to sensitive customer data, resulting in breaches and identity theft.
• Backend Vulnerabilities: Poorly designed or misconfigured backend APIs can expose app architecture to attacks, leading to downtime and compromised performance.
• Unpatched Vulnerabilities: APIs without regular monitoring may miss critical updates, leaving systems susceptible to exploitation.
• Shadow APIs: APIs developed or deployed outside IT governance frameworks create blind spots, posing risks like data leaks and lateral movement by attackers.
• Compliance Risks: Mismanaged APIs often handle data non-compliantly, increasing the likelihood of regulatory violations and penalties under laws like GDPR or CCPA.

The Importance of Comprehensive API Management

Site Reliability Engineers (SREs) employ the following key strategies for secure and efficient API management:

• API Discovery: Cataloging all internal and third-party APIs ensures visibility and uncovers unmanaged shadow APIs to mitigate security and compliance risks.
• Backend Security: Enforcing robust authentication, authorization, and encryption safeguards sensitive data and backend systems.
• Performance Monitoring: Continuous and stress testing helps detect anomalies and identify vulnerabilities under high-load conditions.
• Vulnerability Management: Regular updates and patches address emerging threats, supported by secure coding practices through collaboration with developers.
• Data-Driven Insights: Analytics-driven monitoring of API usage patterns helps optimize performance and proactively address risks.

This concise approach ensures mobile banking apps remain secure, reliable, and compliant.

4 Essential Factors to Strengthen the Security of Mobile Banking Applications

‍1. Specifying Target Audience and Objectives

During mobile banking application testing, one critical factor to consider is defining your target audience and objectives. This step is vital in both the development and testing phases, as it clarifies the users' needs and requirements for creating effective test cases.

To achieve this, businesses must use banking experts and business analysts to perform detailed user persona mapping. This approach enables them to understand customers' banking pain points, potential use cases, and the likelihood of adopting a new solution.

The gathered insights shape long-term business objectives that inform a priority-driven roadmap. Remembering the bigger picture when performing tactical work is vital, as it aligns with the end goal of continuously delighting the users.

By defining the target audience and objectives, businesses can improve the overall mobile banking experience by meeting the users' needs, enhancing security, and ensuring a seamless user interface.

2. Assessing Device Performance to Handle Large Data Volumes 

Mobile banking app testing requires assessing device performance when handling large volumes of data. This includes testing inter-app accessibility, which refers to the ability of one app to access confidential information stored in another app on the same device. While iOS and Android offer high security through features such as permission systems and TouchID, proper usage is necessary to avoid privacy-based online threats.

In addition to inter-app accessibility, device performance is critical to mobile banking app testing. User actions can generate significant data, including user location and login timestamps. Testing must cover every interface by creating distinct datasets to eliminate the effect of a particular feature across interfaces.

Key factors to consider during testing include the device's OS version and display density, which can negatively affect the user experience regarding UI and web page rendering. Other device features, such as CPU type and memory, can also impact specialized applications, making it important to consider them during testing.

‍3. Preparing For Challenges

Mobile banking testing is critical to ensuring a seamless user experience and maintaining the trust of customers. However, there are several challenges that teams may encounter during testing. Proper preparation and planning can turn these challenges into minor speed bumps rather than significant roadblocks. Here are some common challenges to be aware of:

• Limited production data: Many teams new to software testing in the finance industry face the challenge of a lack of existing processes, which can be time-consuming to figure out internally. Engaging experienced QA partners can help define testing, debugging, and reporting processes and ensure the testing strategy succeeds.

• System migration: In some cases, testing strategies may require switching systems mid-stream, dealing with legacy platforms, adjusting to new testing environments, or managing other complex changes. Outsourcing to QA testing experts can help provide guidance or manage the change, allowing the team to focus on other critical areas of the business.

• Inadequate domain knowledge: Limited experience with the financial industry or regulatory compliance testing can hinder a QA team's effectiveness. Partnering with an outside vendor can help mitigate risks associated with testing for security, compliance, and performance. It's important to remember that there is no margin for error in mobile banking testing, as brand perception and customer trust are at stake.

Teams can ensure a smooth and successful mobile banking testing process by addressing these potential challenges head-on and seeking assistance from experienced QA partners.

4. Improving Testing Efficiency

Testing mobile banking applications across all possible device combinations is nearly impossible due to the proliferation of mobile devices with their respective operational differences. Therefore, testers should focus on devices and platforms with significant penetration in specific geographic areas instead of attempting this daunting task. Google Analytics, Dynatrace, and marketing research teams can provide testers with valuable insights into customer app usage patterns, optimizing testing efforts.

To ensure optimal mobile banking application testing, QA teams should prioritize the following areas:

• Functionality testing for a seamless user experience.
• Automation testing reduces manual work and human error, significantly cutting testing time.
• Load and performance testing to guarantee the application can handle session and transaction volumes.
• Security testing to ensure user data safety.
• Regulatory compliance testing to certify that the app meets industry-specific measures.
• API and integration testing to verify that the app works flawlessly with any connected apps, services, or utilities.
• Mobile testing to ensure the application functions well across all supported mobile and tablet devices.

Defining test requirements and building a strategy is crucial to gaining buy-in and feedback from the broader team and stakeholders. It informs the team about the specific testing requirements and how to approach the tests. QA teams or partners should lead these testing initiatives, guiding the team and delivering status reports to key stakeholders.
